About Limestone Technologies

At Limestone Technologies, we are committed to the continuous innovation of software and instrumentation solutions that contribute to making our communities secure and safe, a legacy we can to pass on to future generations. Incorporated in 1999, Limestone Technologies’ journey began in Sex Offender Management with innovate instruments and software designed to aid in the process of offender rehabilitation.

"As a father, I feel a strong sense of responsibility to ensure the safety of our communities. To create products that not only aid in the rehabilitation of offenders, but keeps the bad guys off the streets, gives myself and the Limestone staff a sense of purpose knowing that we are working towards something so significant."

James Brown, Founder and President

Following our early success in Sex Offender Management, Limestone decided to expand our innovative solutions to the credibility assessment market, otherwise known as Polygraph or Lie Detection. In 2003, Limestone unveiled Polygraph Pro Suite, which greatly disrupted the industry. When the industry said something couldn’t be done, Limestone made it happen.  We quickly became one of the international leading providers of polygraph instrumentation and software. But we weren’t done yet. Limestone also had a vision to be the leader in polygraph education and training. In 2017, Limestone acquired the Backster School of Lie Detection, the world’s oldest and longest standing polygraph school to provide the best in class training for the polygraph examiners of tomorrow.

In 2019, Limestone announced its latest venture, non-invasive pre-employment screening. As a start-up business, Limestone has learned from experience the importance of hiring the right candidate the first time, to prevent costly turnover. Limestone partnered with internationally renowned psychologist Dr. Ronald Holden at Queen’s University to develop practical and reliable pre-employment screening solutions to help businesses maximize their resource management and reduce employee turnover. As a deviation from public safety, Recruit Rite, a new division of Limestone Technologies, was formed.

We believe in building lasting customer relationships and we achieve this by providing professional services that is complimented with outstanding after-sales support.
